As used in this Agreement, the term "Title -------------------------- Defect" shall mean any defect which renders title to an Interest, as herein defined, less than Marketable Title. 5.05 Title Procedure. --------------- (a) As used herein, "Title Defect Amount" shall mean, with respect to any reduction of the Net Revenue Interest set forth on Exhibit "A" hereto, an amount calculated by multiplying the reduction in the Net Revenue Interest by the Allocated Value for such affected Interests; with respect to any increase in the Working Interest set forth on Exhibit "A" hereto and assuming no corresponding increase in Net Revenue Interest, an amount calculated by multiplying the increase in the Working Interest by the Allocated Value for such affected Interests; and with respect to any Title Defect that does not cause the Net Revenue Interest set forth on Exhibit "A" to decrease or cause the Working Interest set forth on Exhibit "A" to increase, an amount determined by evaluating the portion of the Interests affected by such Title Defect, the legal effect of the Title Defect, and the potential economic effect of the Title Defect over the life of the affected Interests. The Title Defect Amount as to any particular Interest, however, shall never exceed the Allocated Value therefor. Furthermore, in the event it is determined that the Net Revenue Interests for any affected Interest is greater than set forth on Exhibit "A" hereto or the Working Interests for any affected Interest is less without a corresponding decrease in Net Revenue Interest than set forth on Exhibit "A" hereto, the Purchase Price shall be proportionately adjusted upward by multiplying the increase in the Net Revenue Interest by the Allocated Value for such affected Interest or multiplying the decrease in the Working Interest by the Allocated Value for such affected Interest. Increases or decreases in the Working Interest without a corresponding increase or decrease in the Net Revenue Interest shall be evaluated by rerunning the economics for the affected Interest to determine the impact on the Allocated Value for such affected Interests. Notwithstanding any terms contained in this Agreement to the contrary, no -13- adjustment to the Purchase Price for Title Defects and Environmental Defects shall be made unless the sum of such Title Defect Amounts and Environmental Defect Amounts is more than Two Hundred Fifty Thousand and No/100 Dollars ($250,000.00). This $250,000.00 sum is a threshold, not a deductible, and if this threshold is exceeded, the Purchase Price shall be adjusted by the total sum of these defects. In addition, this threshold amount shall apply independently to increases in the Purchase Price for the reasons set forth in this Section 5.05(a), and the amounts attributable to such increases shall not be netted against the downward adjustments to the Purchase Price to determine whether or not a Purchase Price adjustment should be made. Notwithstanding any terms contained in this Agreement to the contrary, no Title Defect shall be asserted by Buyer unless the Title Defect Amount is at least Twenty Thousand and No/100 Dollars ($20,000.00). This $20,000.00 threshold shall likewise apply to any upward adjustment sought by Seller under this Section 5.05(a). (b) If Buyer discovers any Title Defect, Buyer shall give Seller notice of such Title Defect no later than fifteen (15) days prior to the Closing Date. Such notice shall be in writing and shall include (i) a description of the Title Defect and (ii) the Title Defect Amount therefor. Buyer shall be deemed to have waived all Title Defects to which Buyer has not given timely notice to Seller thereof. (c) Seller shall notify Buyer in writing no later than five (5) days before the Closing Date whether it elects to cure the alleged Title Defect. If Seller has elected to cure the Title Defect, then the Interests subject to the Title Defect shall not be assigned at the Closing and Seller shall use commercially reasonable efforts to cure such Title Defect during a period ending sixty (60) days after Closing. Notwithstanding the foregoing, Seller shall be under no obligation to cure any Title Defect unless Seller otherwise expressly agrees in writing to cure such Title Defect. (d) With respect to any Title Defect that Seller elects not to cure, Seller shall have the option to: (i) Exclude the Interest, including pipelines and other personal property necessary to operate the particular Interest subject to the Title Defect, in which event the Purchase Price shall be reduced by the Allocated Value of the excluded Interest; or (ii) If Buyer nad Seller so agree, sell the Interest subject to such Title Defect to Buyer and the Purchase Price shall be reduced by the Title Defect Amount. (e) Notwithstanding any terms contained in this Agreement to the contrary, in the event the aggregate amount of (i) the Title Defects and (ii) the Environmental Defect Amounts and which Seller does not timely agree to cure, excluding exercised preferential rights to purchase exceeds twenty percent (20%) of the Purchase Price, either Seller or -14- Buyer may elect to terminate this Agreement and Buyer shall be entitled to an immediate refund of the Deposit. 5.06 Consents and Preferential Rights. -------------------------------- (a) If any third party consent to the sale and transfer of the Interests is not obtained prior to the Closing, Buyer shall not treat that portion of the Interests subject to such consent requirement as a Title Defect if such consent is customarily secured after the Closing or such consent does not materially affect the value of the affected Interests if such consent were withheld. (b) If any of the Interests are subject to a preferential right to purchase, Seller shall in a good faith, prior to the Closing Date, attempt to notify each third party which holds a preferential right to purchase covering that portion of the Interests subject thereto. If the notice period under any preferential right to purchase has not expired prior to the Closing Date, Buyer shall nevertheless purchase that portion of the Interests which may be affected by the exercise of such preferential right but the Interests subject to such unexpired preferential right shall not be treated as a Title Defect. If after the Closing any party holding a preferential right to purchase elects to exercise same, Buyer shall then coordinate with Seller in connection with the execution by such third party of a purchase and sale agreement substantially in the form hereof. Buyer shall be due any consideration paid by such third party upon the exercise of such preferential right to purchase in exchange for Buyer delivering such third party an assignment for that portion of the Interests affected by the exercise of such preferential right. 5.07 Environmental Procedure. ----------------------- (a) Prior to the Closing Date, Buyer may conduct a field inspection of the Interests and Buyer may further secure, at its sole risk, cost and expense, an environmental audit of all or any of the Interests. If obtained, Buyer shall immediately furnish a copy of such environmental audit to Seller and the contents of such environmental audit shall remain confidential unless required to be disclosed by any rule, order or governmental proceeding. (b) As used herein, "Environmental Defect" shall mean any material environmental defect relating to the Interests in the nature of environmental pollution or contamination, including pollution of the soil, ground water or the air, and which is a violation of environmental or land use laws, rules, regulations, or orders of appropriate state or federal regulatory agencies. (c) As used herein, "Environmental Defect Amount" means the cost to remediate such Environmental Defect in accordance with applicable environmental laws. Notwithstanding any terms contained in this Agreement to the contrary, no adjustment to the Purchase Price shall be made unless the sum of such Title -15- Defect Amounts and Environmental Defect Amounts is more than Two Hundred Fifty Thousand and NO/100 Dollars ($250,000.00). This $250,000.00 sum is a threshold, not a deductible, and if this threshold is exceeded, the Purchase Price shall be adjusted by the total sum of these defects. In addition, this threshold amount shall apply independently to increases in the Purchase Price for the reasons set forth in this Section 5.07(a), and the amounts attributable to such increases shall not be netted against the downward adjustments to the Purchase Price to determine whether or not a Purchase Price adjustment should be made. Notwithstanding any terms contained in this Agreement to the contrary, no Environmental Defect shall be asserted by Buyer unless the Environmental Defect Amount is at least Twenty Thousand and No/100 Dollars ($20,000.00). (d) If Buyer discovers any Environmental Defect, Buyer shall give Seller notice of such Environmental Defect no later than fifteen (15) days prior to the Closing Date.

Buyer shall be deemed to have waived all Environmental Defects to which Buyer has not given timely notice to Seller thereof. (e) Seller shall notify Buyer in writing no later than five (5) days before the Closing Date whether it elects to cure the alleged Environmental Defect. If Seller has elected to cure the Environmental Defect, then the Interest subject to the Environmental Defect shall not be assigned at the Closing and Seller shall use commercially reasonable efforts to cure such Environmental Defect during a period ending one hundred eighty (180) days after Closing. Notwithstanding the foregoing, Seller shall be under no obligation to cure any Environmental Defect unless Seller otherwise expressly agrees in writing to cure such Environmental Defect. (f) With respect to any Environmental Defect that Seller elects not to cure, Seller shall have the option to: (i) Exclude the Interest, including pipelines and other personal property necessary to operate the particular Interest subject to the Environmental Defect, in which event the Purchase Price shall be reduced by the Allocated Value of the excluded Interest; or (ii) If Buyer and Seller shall so agree, sell the Interest subject to the Environmental Defect to Buyer and the Purchase Price shall be reduced by the Environmental Defect Amount. Notwithstanding any terms in the Section 5.07 to the contrary, with respect to the Watt No. 2 well and the Tveit Saltwater Disposal System ("Tveit et al Properties"), if Buyer asserts an Environmental Defect on the Tveit it al Properties, Buyer shall have the option, but not the obligation to accept an indemnity from Seller which is acceptable to Buyer -16- (g) Notwithstanding any terms contained in this Agreement to the contrary, in the event the aggregate amount of (i) the Environmental Defect Amounts and (ii) the Title Defect Amounts set forth in Section 5.05 hereinabove, and which Seller does not timely agree to cure, exceeds twenty percent (20%) of the Purchase Price, either Seller or Buyer may elect to terminate this Agreement and Buyer shall be entitled to an immediate refund of the Deposit. 5.08 Casualty Loss. If, prior to the Closing, all or any portion of the -------------- Interests shall be destroyed by fire or other casualty, or if any portion of the Interests shall be taken in condemnation or under the right of eminent domain, or if proceedings for such purposes shall be pending or threatened (collectively "Casualty Losses"), except as provided below, this Agreement shall remain in full force and effect notwithstanding any such destruction or taking, and Seller shall at Closing pay to Buyer all sums paid to Seller by reason of such destruction or taking. In addition, Seller shall assign, transfer and set over unto Buyer all of the right, title and interest of Seller in and to any unpaid awards or other payments arising out of such destruction or taking. Seller shall not voluntarily compromise, settle or adjust any amounts payable by reason of such destruction or taking without first obtaining the written consent of Buyer. Notwithstanding the foregoing, in the event the total value of Casualty Losses exceeds twenty percent (20%) of the Purchase Price, either Buyer or Seller may elect to terminate this Agreement and Buyer shall be entitled to an immediate refund of the Deposit. In addition, the Purchase Price shall be reduced by the amount of Seller's deductible under any applicable policy of insurance or other sums not covered by Seller's insurance or any shortfall in the unpaid awards insofar as the same pertain to payments arising out of the destruction or taking of the affected Interests. 5.09 Plugging and Abandonment. Upon Closing, Buyer shall assume all of ------------------------- Seller's plugging, replugging, abandonment, removal, disposal and restoration obligations associated with the Interests acquired hereunder. Such obligations being assumed shall include, but not be limited to, all necessary and proper plugging and abandonment and/or removal and disposal of all of the Wells, whether pre-existing or drilled by Seller, and all structures, personal property and equipment located on or associated with the Leases, the necessary and proper capping and burying of all associated flow lines, and any necessary disposal of naturally occurring radioactive material (NORM) or asbestos except those matters which are asserted as Environmental Defects and which remain uncured.
